Which feature allows an administrator to revert back to the previous version of a VM template?

The feature that allows an administrator to revert back to a previous version of a VM template is the Content Library. The Content Library in VMware provides a centralized location for managing and storing VM templates, ISO images, and other files needed for virtual machine provisioning. One of the significant advantages of using a Content Library is its support for versioning. This feature enables administrators to maintain multiple versions of templates, thereby allowing for easy reversion to a previous state if needed.

By utilizing the versioning capabilities within the Content Library, an admin can efficiently manage template updates and roll back to prior configurations without losing any critical information or workflows. This is particularly useful in environments that require frequent changes and testing, ensuring a streamlined process for using and updating templates while maintaining operational continuity.

Other features listed serve different purposes within the VMware environment. VM Snapshots are typically used to capture the state of a VM at a particular point in time, allowing for quick recovery but not specifically focused on managing template versions. Storage vMotion pertains to the migration of a VM's storage from one datastore to another without downtime, and VMware Tools enhances the performance and management of VMs but does not manage template versions.
